摘要：
The invention relates to an orthotic or prosthetic joint device with an upper part (2) and a lower part (3) arranged in a hinged manner on the latter, and fastening means (4, 5) for securing the joint device (1) on a user, with at least one hydraulics unit (10) between the upper part (2) and the lower part (3), which hydraulics unit (10) has a piston (12) that is movable in a housing (11) with an extension chamber (14) and a flexion chamber (15) and that is coupled to the upper part (2) or the lower part (3), and which hydraulics unit (10) is assigned a pressure supply device (20) with a pump (21) and a pressure accumulator (23) via which the piston (12), controlled by a control device (60), is subjected to a pressure, wherein the pump (21) can be operated in generator mode, the pressure accumulator (23) can be coupled drivingly to the pump (21), and the hydraulic fluid can be conveyed by the pressure accumulator (23) through the pump (21) to the hydraulics unit (10).
